Selenium 选择表中的第一行，即使我正在遍历行

Question

我真的不确定这里发生了什么，也无法弄清楚，所以希望有人可以帮助我。

基本上，我是在选择一个表，然后查找该表中的所有行。从这里，我遍历行并选择三个复选框并检查它们是否被选中。但是，我为每一行得到的结果总是第一行。例如

错误 真的 假的

那么……

错误 真的 假的

何时应该更改每一行。

Python/Selenium 代码：​​

table = driver.find_element_by_xpath("//table[@id='tableMscRatesModal']/tbody")
rows = table.find_elements(By.XPATH, "//tr[@class='ng-scope']") # get all of the rows in the tables

for row in rows:
    print(row.text)

    manager_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='1']")
    standard_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='2']")
    no_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='3']")

    print(manager_box.is_selected())
    print(standard_box.is_selected())
    print(no_box.is_selected())

    if not (manager_box.is_selected() or standard_box.is_selected() or no_box.is_selected()):
        standard_box.send_keys(Keys.SPACE)

我在下面包含了两行的示例。这对 x 行重复完全相同。

当使用xpath从另一个元素中定位一个元素时，您需要使用当前上下文.

for row in rows:
    manager_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='1']")
    standard_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='2']")
    no_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='3']")

如果你使用列表，你也可以简化你的代码

checkboxes = row.find_elements_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')]")
for checkbox in checkboxes:
    print(checkboxes.is_selected())

如果你放弃print(row)，甚至更远

checkboxes = row.find_elements_by_xpath("//table[@id='tableMscRatesModal']/tbody//tr[@class='ng-scope']//td/input[@type='radio']")
for i in range(0, len(checkboxes), 3):
    print(checkboxes[i].is_selected())
    print(checkboxes[i + 1].is_selected())
    print(checkboxes[i + 2].is_selected())
